Hobbit core dump every 5 minutes

Hi Guys, today my hobbit server started throwing up purple alerts for all my network (conn) and various other tcp connection tests. I noticed that a core file was being created every 5 minutes. Here is what gdb has to say - [hobbit at monitor server]$ gdb bin/hobbitd core.4115 GNU gdb (GDB) Red Hat Enterprise Linux (7.0.1-23.el5_5.2) Copyright (C) 2009 Free Software Foundation, Inc.

Help with label names in bb-hosts
by Sridhar.Adapalli＠hhsc.state.tx.us 18 Jan '11

18 Jan '11

Hi When I increased the label name for each server in bb-hosts, the number of metrics parameters reported suddenly dropped. I used to get "conn", "cpu", "disk", "http", "info", "ldap", "memory", "netstat", "procs", "sslcert", "svcs", "trends", "uptime", "who". But after I increase the label name size, I only got back a subset. It looks like it is not able to fit in the page all the parameters. Is there a way to get around this issue, such as decrease the font size of the label? Thanks -- Sridhar

Hobbitd and bbproxy at the same host
by rower.master＠gmail.com 18 Jan '11

18 Jan '11

Hi All, Is there someone on the list that could share with me a working configuration of hobbitlaunch.cfg and hobbitserver.cfg for running hobbitd and bbproxy at the same host on different ports? I´ve tried some configurations already described on the list but without success. Thanks in advance, Mario.

Scheduled disable causes crash?
by johan.sjoberg＠deltamanagement.se 18 Jan '11

18 Jan '11

Hi! During the last month, we have had some problems with Xymon when using scheduled disabled (added from the web interface). The first problem we had was on September 17th, when hobbitd crashed while/after running the scheduled disable. We got the following error in hobbit.log 2010-09-17 05:00:00 Fatal error in select: Bad file descriptor 2010-09-17 05:00:00 Setup complete After that incident, I enabled verbose logging for hobbitd, and turned up the logging for some other process as well. This morning at 06:00 we had a new scheduled disable. This time hobbitd just stopped logging after running the disable. The web interface did not work correctly. When clicking a test, an "Internal server error" message was displayed. Also, the bbgen test went purple (last update at 05:59:26). The only errors I have been able to find in the logs are in bb-display.log: 2010-10-05 06:00:26 xstrdup: Cannot dup NULL string 2010-10-05 06:01:26 xstrdup: Cannot dup NULL string 2010-10-05 06:02:27 xstrdup: Cannot dup NULL string 2010-10-05 06:12:30 xstrdup: Cannot dup NULL string 2010-10-05 06:13:35 xstrdup: Cannot dup NULL string 2010-10-05 06:14:39 xstrdup: Cannot dup NULL string 2010-10-05 06:24:40 xstrdup: Cannot dup NULL string 2010-10-05 06:25:41 xstrdup: Cannot dup NULL string 2010-10-05 06:26:42 xstrdup: Cannot dup NULL string 2010-10-05 06:36:47 xstrdup: Cannot dup NULL string 2010-10-05 06:37:48 xstrdup: Cannot dup NULL string 2010-10-05 06:39:54 xstrdup: Cannot dup NULL string 2010-10-05 06:40:54 xstrdup: Cannot dup NULL string 2010-10-05 06:41:54 xstrdup: Cannot dup NULL string Xymon was restarted at 06:43. Here is the hobbit.log from the time. It was too large to paste in the mail. http://pastebin.com/JuU0BHje We are running Xymon 4.2.3 on CentOS 5. Best regards, Johan Sjöberg

Execute a script on the client side
by meepmeep＠fantasya.org 17 Jan '11

17 Jan '11

Hi I use Xymon to monitor multiple server. Since last week, one of my server get a suspicious behavior : the openvpn process was still up, but the default route changed, making it appears on the web with its original IP address (and not the openvpn gateway). I decide to use xymon to detect this, but, I'm kind of stuck to execute the script on the client side I follow this "howto" : http://en.wikibooks.org/wiki/System_Monitoring_with_Xymon/Other_Docs/HOWTO#… But, finally, the script give my the public address of the SERVER side. So, am I doing something wrong with the server side module ? Is there an option to push the test on the client side ? Or, must I put the script on the client side (~hobbit/client/ext/), like describe here : http://en.wikibooks.org/wiki/System_Monitoring_with_Xymon/Other_Docs/HOWTO#… ? (I know, the name "server side module" is obvious, but I thought xymon was able to keep client configuration on server side) -- Nicolas G. / meepmeep [EuropNet.org Admin] "Procrastinators: Leaders of Tomorrow"

Xymon 4.3.0-beta3 on iPad - tester needed
by henrik＠hswn.dk 15 Jan '11

15 Jan '11

Hi, I've had one report that the new Xymon menu (the one using CSS) does not work on an iPad. The same user reported that it *does* work in Apple's Safari browser. So I'm curious if one of you have an ipad and could verify this for me ? The http://www.xymon.com/ website uses the new CSS menu, so just point your iPad browser there and let me know if the menus are working or not. On a slightly related note, has anyone had problems installing Safari for Windows ? My installation hangs half-way through the installation while registering DLL's - so much that only a reboot can clean it up. Regards, Henrik

Is there any way to set up xymon so that it will detect a missing disk? I had a SAN disk on a Windows box go missing for an hour or so last night and it wasn't detected. Thanks, Larry Barber

Repeat: Client test problems on Xymon server 4.2.3
by novosirj＠umdnj.edu 14 Jan '11

14 Jan '11

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I had posted a message on this before and never really got anywhere with it. I just re-read all of the replies from last time and none of them really gave me anything to go on (they say look at logs, but none end up being created). First off, here is the section that starts the Xymon client from within the Xymon server's hobbitlaunch.cfg: # "hobbitclient" runs the Xymon client. The client is installed automatically # when you install a Xymon server (presumably, you do want to monitor the # Xymon server ?), but there's no need to have two hobbitlaunch instances # running at the same time. So we'll just run it from here. # Note: If you are using another client package, you should disable this one. [hobbitclient] ENVFILE /opt/xymon-4.2.3/client/etc/hobbitclient.cfg NEEDS hobbitd CMD /opt/xymon-4.2.3/client/bin/hobbitclient.sh LOGFILE $BBSERVERLOGS/hobbitclient.log INTERVAL 5m I checked to see where this LOGFILE is supposed to be going: BBSERVERLOGS="/opt/xymon-4.2.3/log" So I looked in there: > ls -la /opt/xymon-4.2.3/log/ total 3228 drwxr-xr-x 2 xymon daemon 512 Jan 13 15:48 . drwxr-xr-x 9 root root 512 Sep 16 2009 .. - -rw-r--r-- 1 xymon daemon 1550037 Dec 23 15:47 bb-network.log - -rw-r--r-- 1 xymon daemon 74080 Jul 26 16:39 bb-retest.log - -rw-r--r-- 1 xymon daemon 9314 Jan 13 15:48 hobbitlaunch.log - -rw-r--r-- 1 xymon daemon 5 Jan 13 15:48 hobbitlaunch.pid No such file. So I checked the hobbitlaunch.log sitting here: 2011-01-13 15:48:06 hobbitlaunch starting 2011-01-13 15:48:06 Loading tasklist configuration from /opt/xymon-4.2.3/server/etc/hobbitlaunch.cfg That file exists, as I copied the above [hobbitclient] section out of t.The last thing I can think of is that maybe $BBSERVERLOGS is not defined in the context in which it is needed. Beyond that, I'm totally out of ideas. It appears as if this section is completely ignored. On both of my machines, if I don't start the client (by changing to the client directory and doing ./runclient.sh start), it doesn't get started.

Problem with file owner/group check
by ian.marsh＠hants.gov.uk 14 Jan '11

14 Jan '11

We recently encountered a problem with directory permissions on one of our web servers and so decided to update our Xymon installation (v4.2.3) to monitor it. Unfortunately I think I've found a bug in the code that facilitates this. In the hobbit-client.cfg file we have a test like this: FILE /var/somefile mode=755 owner=root groupid=root yellow The owner test works fine but the group test doesn't, instead it say that the file should be owned by group 'd=root'. Further investigation shows that the owner test also fails in the same way if we use the 'ownerid=root' variation of the owner test. It's almost as if the code is assuming that the first 6 characters of the token is the name and everything else is the value. This works fine with the 'owner=root' variation but fails dismally with the 'ownerid=root' and 'groupid=root' variations. It would be fine if we could use 'group=root' but as that's a reserved word it's not allowed. Unfortunately my C coding is virtually non-existent, I can get by with reading it but not writing it! Has anyone encountered this before and written a patch for it? Or has it been fixed in the 4.3.0 beta? Thank you, Ian Marsh IT Service Operations - Network Services
